Abstract: An information processing system that acquires video data captured by an image pickup unit; detects an object from the video data; detects a condition corresponding to the image pickup unit; and controls a display to display content associated with the object at a position other than a detected position of the object based on the condition corresponding to the image pickup unit.

Abstract: A transmission device includes a transmission processing circuitry configured to transmit and receive signals to and from another transmission device through a transmission path, a first memory, a first processor coupled to the first memory, configured to perform monitoring control of the transmission processing circuitry, a second memory, and a second processor coupled to the second memory, configured to perform monitoring control of the transmission processing circuitry on behalf of the first processor when a failure occurs in the first processor, wherein when a failure occurs in a monitoring control system that performs monitoring control of the other transmission device, the second processor performs monitoring control of the other transmission device by transmitting and receiving control signals to and from the other transmission device.

Abstract: A network monitoring method executed by a plurality of relay devices within a network includes stopping, by a first relay device, transfer of a data frame received via a port at which a loop in the network is detected when the loop is detected; transmitting a first search frame configured to identify one or more relay devices included in a path in which the loop has occurred; receiving, by a second relay device, the first search frame; transmitting a second search frame obtained by storing identifying information identifying the second relay device in a data region of the first search frame; and identifying, by the first relay device, the one or more relay devices included in the loop using information included in the data region of a third search frame generated from the second frame by passing through one or more relay devices, when the third search frame is received.
